I want to make it so if a visitor skips pass the doorway/intro page. The server checks if they got a cookie. If they don't, they are redirect to the doorway page. At the doorway they click Enter and it sets the cookie in their browser, so when the come back they don't see the door way page anymore. How can I do this? I've seen this done before. Age verification scripts use this. But my movtive is to so when click Enter it sets off a pop-under. So get extra pop-unders per visitor
Is there a point to the intro page? Do you have a plan for people who do not ever accept cookies? Are you trying to prevent people from ending up in some middle part of your site via a link at another site?
Doing this is probably too complicated. Nevermind...>.> But to answer your question Its for a my Top proxy site that recieve few hundred visitors a day. I just want them to see the doorway page So get extra pop-unders off them when they click enter.
